Graco's Magnum series of sprayers has been one of the most successful product lines they ever produced IMHO. Homeowners and professionals use these machines to paint just about anything you can imagine and they perform admirably. Like all the sprayers, they need to be kept clean and do require looking after when the job is done and you're tired. And parts do break and wear out. O-Gee has a good supply of the most popular parts on hand for these sprayers and we can get the rest from Graco usually in short order.
